According to Karl T. Ulrich, product architecture is the scheme by which the function of a product is allocated to physical components. In fact it is the adaptation of the system architecture methodology from system engineering into the field of commercial product design.
Thus arranging the architecture of the product consists of three aspects:-
- Functional Architecture – Deciding all the functions that the product must perform (and this should be related to the requirements) and then organising these into a functional structure.
- Physical Architecture – Deciding the physical structure of modules and components and assigning functions to these physical entities.
- Interface Specification – Determining the interfaces between all the physical components.
This type of approach is particularly important in modular design so that a common platform can be shared and in mass customisation.
